NGC 7000 - North America Nebula

This is a bit of a case of polishing the proverbial, but I've been working with a new CLS filter on loan from a local telescope store (the Astronomik CLS). Without true dark this time of year imaging emission nebulae is a bit tricky, but it's hard to resist this target as it rises in the clearest, darkest portion of my backyard sky.

It's pretty clear that my camera is not taking in very much red channel information, which made imaging and processing very difficult. Inspecting the RAW files revealed that the red channel was severely underexposed. This suggests, to me, that it's probably worth astromodifying.

I did two runs at processing this - first, with my typical workflow, and then again using a starless version of the nebula to stretch the image further while retaining as much detail as I could. I'm not 100% happy with either of them, but I'm calling it a day for now, until I can get some true dark, and maybe have my IR filter removed from my T3i.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
